I was trying to follow a program written I think in C language. Came to a point where above piece of code was written and could not determine what this code mean. I checked the C library reference guide, but it didn't help me much.
// toggle pin 11 on compare TCCR2A = _BV(WGM21) | _BV(COM2A0); TCCR2B = _BV(CS20);
// 38kHz timer OCR2A = (F_CPU/(IR_CLOCK_RATE*2L)-1);
Could anyone enlighten me, please.
